The Current Key Problems and Potential Solutions for Geosciences Data Sharing in China

China's geosciences data sharing has progressed significantly but is still facing some key questions that need to be solved Because of the data’s insufficiency, it has limited use in modern scientific research. The documents and metadata for the data are insufficient. The scientific data service is dated. The data application procedure is troublesome, etc. All this has become a bottleneck affecting the progress of China’s scientific data sharing. Considering the reality of China, some potential solution have been proposed, which include changing the scheme of data integration, perfecting metadata and documentation, emphasizing data service, simplifying the application procedure, enhancing the shared consciousness in science and technology fields, establishing national data centers, and realizing sustainable data sharing.
